Abstract

We demonstrate compact waveguide splitter networks in silicon-on-insulator (SOI) rib waveguides using trench-based splitters (TBSs) and bends (TBBs). Rather than a 90° geometry, we use 105° TBSs to facilitate reliable fabrication of high aspect ratio trenches suitable for 50/50 splitting when filled with SU8. Three dimensional (3D) finite difference time domain (FDTD) simulation is used for splitter and bend design. Measured TBB and TBS optical efficiencies are 84% and 68%, respectively. Compact 105° 1×4, 1×8, and 1×32 trench-based splitter networks (TBSNs) are demonstrated. The measured total optical loss of the 1×32 TBSN is 9.15 dB. Its size is only 700 µm×1600 µm for an output waveguide spacing of 50 µm.
